T o all whom t may concern.'

13e it known that I, .JosnrH H. BRISKIN, a citizen of the United States, residing at Los Angeles, California,have invented a certain newy and useful Forming Machine, of which the following is a specification.

My object is to make a forming machine especially for making thewater tube pieces of a radiator core7 and my invention consists of the novelfeatures herein shown, described and claimed.

A leading feature of my invention `consists of the combination of a reel adapted to receive a reel of stock, an adjustablegage to receive the stock from the reel, corrugating rolls which pull the stock from the reel through the gage and push the corrugated stock forwardly to be finished, adj ustable center finishing dies, and adjustable side finishing dies.

Another leading feature consists of ad-v justable reciprocating finishing dies, so that stock of various widths may be readily used.

. Another leading feature consists of connect-inv reciprocating nishing dies to `corrugating rolls, so as to take stock from a roll, corrugate the stock, and feed the corrugated stoel; to the finishing dies.

Referring to the drawings in detail:

The forming machine is builtv upon a punch press having a base 1, a bed 2, uprights .3 and 4, a head 5, a'slide 6, a crank 7, and a fly wheelS, all of the ordinary construction.

A supporting plate 9 fits between the lower ends of the uprights 3 and 4 and is secured in place by cap screws 10,inserted upwardly through the extension 11 of the bed 2. Bearings 12 extend backwardly and downwardly from the plate 9, a shaft 13 is mounted in the bearings 12, housing blocks 14 extend upwardly from the bearings 12., and the supporting arms 15 .and

16 extend backwardly from the junction of the bearings 12 and housing blocks 14. l

The reel 17 is a shaft mounted loosely through the rear ends of the supporting arms 15V and 16 and av roller 0n the shaft, and the 11011718 of radiator metal is mounted upon the reel.

YThe adjustable gage 19 consists of the following details: y

The lower plateyk 2O hasy its sidesbent downwardlyto fit between the arms 15 and 16; the upper plate 21 has its sides bent upwardly and the backgage plate 22 Vfits between the back sides of the plates 2O and 21, and rivets 23 hold the three pieces together. The upper plate 21 has openings 24 through which the stock 18 can be seen. The down and upV turnedvends of the plates 20 and 21 are secured to the arms 15 and 16 by screws.

plate 25 slides through a slot in the arm 16 between the plates 2O and 21 and has an up turned outer end to serve as a handle 26. Spaced screw holes 27 are formed through the plates 2O and 21 and nuts 28 are soldered against the lower face of the plate 2O in line with the screw holes. The gage plate 25 has holes near its inner edge and screws 29 are removably inserted downwardly through the parts into the nuts 28. The stock 18 is inserted between the plates A20 and 21 against the back gage 22, the

front gage is moved against the stock and the screws inserted and tightened to pull the plates together. By moving the screws the gage is adjusted to different widths of stock, and the gage causes the stock to run straight from the reel to the corrugating rolls.

The details of the corrugating rolls y are as follows:

A roll 31 is fixed upon the shaft 13 between the bearings 12. Springs 32 are mounted in the housing blocks 14, bearings 33 are slidingly mounted in the housing blocks 14 against the springs 32, a shaft 34 is mounted in the bearings 33, and a roll 35 is 'mounted upon the shaft 34 between the housing blocks and in line with the roll 31. The bearings 33 slide up and down and the springs32 are under the bearings and serve to move the roll 35 upwardly away from the roll 31. Caps 36 are removably mounted upon the housing blocks and adjustably operated screws 37 are ,inserted downwardly through the caps against the bearings 33, so that by manipulating the screws 37 the roll 35 is adjusted to or from t-he roll 31.

The rolls 31 and 35, as shown, have matching teeth 38 and grooves 39. At the point of each tooth 38 is a punch seat 40 and at the bottom of each groove is a puncn 41 to match the punch seat. The punch seats 40 and punches 41 are used in making the air cooling spacer pieces of the radiator core, but are not used in making the water tube pieces set vup in this case.l The spacer pieces are made on the same machine by changing the dies. YVhen it is desired to make the water tube pieces, the screws 37 are manipulated to move the roll 35 away from the roll 31 until the punches 41 are out of operative relation with the punch seats 4() and then the rolls simply corrugate,

the stock an'd draw it from the reel 17 through the gage 19 and push it on tothe finishing dies. The fiat stock 13 passing through the rolls 30 becomes the corrugated stock 42 and this runs over the spring stripper 43, which is a plate pivoted at its rear end and has a spring 44 under its forward end, so as to run the stock over the lower finishing dies and allow the stock to be pressed down. into the dies and the tension of the spring 44 raises the stock out of the dies for the next movement.

The corrugated stock 42 passes between the lower center finishing dies 45 and the upper center finishing dies. 46, then between the lower side finishing dies 47 and the upper side finishing dies 48, then over the spring stripper 49 which is similar to the stripper 43, and then over the curved guide plate 50.

The details of the center finishing dies 45 and 46 and the side finishing dies 47 and 48 are as follows: Y

The lower finishing dies 45 and 47 are assembled together and mounted on the bolster plate 51 and the bolster plate is mounted on the bed 2. A dove tail slide way or seat 52 is formed in the upper face of the bolster plate 51 and the dove tail anchor plates 53 and 54 fit in the seat 52. Vertical longitudinal slots 55 and 56 are formed in the anchor plates from their outer ends and near their front sides and screw holes 57 and 58 are formed near the outer ends of the slots, the upper ends of the holes being countersunk. Screws 59 are inserted downwardly into the holes 57 and 58 and have tapered shoulders just below their heads to lit thecountersinks, and the screwsv are short, so that when the anchor plates are placed in proper positionsin the seat 52, the screws 59 are tightened thus expand ing the anchor' plates and holding them rigid upon the bolster plate.V The side bar die plates 60 and 61 are secured against the inner ends of the anchor plates 53 and 54 by countersunk cap'screws 62. The extension bar 63 is recessed into the lower faces of the anchor plate 54 and side bar 61 and held rigid by screws or rivets. A recess 64 is formed in the lower yfaces of the anchor plate 53 and side bar 60 to receive the extension bar 63 so that the side bar 61 may be moved toward or away from the side bar 60. The intermediate die plates 65, 66, 67 and 68 are recessed in their lower faces to tit upon the bar 63 and tit closely side by side and against the inner faces of the rear halves of the side bars 60 and61. Rods 69 and 70 are inserted through all the parts parallel with the bar 63. The yielding die plates 71 and 72 fit against the inner faces of the front halves of the side bars 60 and 61. Stud bolts 73 and 74 are inserted through `vertical slots in the plates 71 and 72 into the side bars 60 and'61. Spring seat plates 75 and 76 are recessed into the lower faces of the bars 60 and 61 and extend under the ends of the die plates 71 and 72 and springs 77 and 78 it between the plates 75 and 76 and thevdie plates 71 and 72.

The die plates 65, 66, 67 and 68 and theV corresponding portions of the die plates 60 and 61 constitute the lower adjustable center finishing dies 45, and the die Vplates 71 iso and 72 and the correspondingpontions Aof the die plates and 61 lconstitute `the lower side finishing dies .47. The adjustment is made by putting in or taking out one 4or more of the die plates 65, 66, 67l and 68, and

'moving the anchor plates '54 and 58, to-

, rlhe die.l

wards or away from each other. plates 65, 66, 67 and 68 are made in various widths so as to secure any desiredV adjust-v ment. l

The upper finishing dies 46 and 48 are shaped and adjusted to match the lower finishing dies 45 and 47. The anchor plates 79 ant 80have dove tail seats 81 and 82 iii-their upper faces and the dove tail 88 of the punch plate 84 fits in the'seats. The extension bar 85 is secured against the lower face of the anchor plate 80 and lits slidingly against the lower face vof the anchor plate 7 9. The side bar die plates 86 and 87. are secured against the lower faces of 'the anchor plates 79 and 80 by screws 88 and 89 and have recesses to receive'the bar'85. The intermediate die plates 90, 91, 92 and 98 are recessed to slide upon the bar 85 and match the bars 65, 66, 67 and 68. Rods and 95 are inserted through all the die plates parallel with Vthe bar 85. lThe yielding die plates 96 and 97 are connected to the side bars 86 and 87 in the same mann-er as the die plates 71 and 72. The anchor plates 7 9 and 80 are held in place by set screws The corrugations of the stock 42 are regular half round curves up and down and the center finishing dies 45 and 46 sharpen the 'up curves to produce the ribs 99 to engage the air cooling spacer piece ofthe radiator core. The edges 100 of the lowerdies engage in t-he sharp grooves 101 ofthe upper dies. The spacing of the dies are the same as the spacing of the corrugating rolls. The side finishing diesv47 and 48 reform the edges of the stock yto produce the flat longitudinally extending faces 102 in line with the-ribs 99, the longitudinally extending flat faces 103 in line with the curves 104 between the ribs 99, and the inclined flat faces105 connecting` the faces 102 and 103, The 'faces 102 are drawn down slightly relative to the Vribs 99 and the faces 103 are drawn down considerably relative to the curves 104, so that when the pieces are placed together bottom to bottoni the faces 102, 108 and 105 lit close together and form an edge 106 with the ribs 99 projecting longitudinally outwardly alternately from opposite sides and between the edges the water space 107 is formed.

The yielding die plates 71 and 72 and 96 and 97 normally project above the rigid die plates and may rock slightly and serve to register the stock accurately in the dies before the final action.

The anchor plates 54 and 80 are set so as to bring the outer sides of the die plates 61 and 8611i line with the back gage 22, then larly step-by-step.

the intermediate )dies 65, 66, `67 and 68 zand 90,91, and 93 vare applied to make the proper width and the anchor plates lfifl-.antlv 7,9 applied. lVhen the width of stock is changed the intermediate dies yare changed accordingly.

A guidev flange 108 is mounted upon the H guide plate 50 in line with the back gage 22 and an adjustable guide flangeV 109V is mounted upon the guide plate to engage the front edge of the stock, so that the vstock will run straight through the machine.

An adjustable brake construction 11:0 is applied to the rear end of the shaft 13 vsoas to hold the' corrugating rolls from spinning. A brake wheel A1 is fixed Ion ther shaft 13.

An angle rbracket A is secured to the sup-4 port-ing arm 15 by bolts B. The brake band has a circular portion C fitting the wheel A1',V

an end portion D secured tothe bracket 'A by a -bolt E, and an end portion F parallel with the 'portion D. A vbol-t -G connects the portions D and F so asto adjust the tension ofthe portion C upon the wheel A1.

he details of the step-bystep connection between the rotary Corin-'gating rolls 30 and the reciprocating finishing oies are as follows: i ci A ratchet wheel 111 is fixed upon the shaft 13 in front of the front bearing 12:`

rolls a step at each operation of the recipro! eating dies, so as to advance lthe stock regu- The head11'7 is adjustable so as to vary the stroke of the -pawl 114 to take more or less teeth 112 at a step.

l prefer to advance the stock the amount of three teeth 11.2 at each operation, but the partsv may be assembled and adjusted for more or less advancement by means of the adjustable head 117 on the crank 116.

Thus I have produced a machine which takes metal from a roll and progressively and continuously forms the water tube pieces of a radiator core, and which may be readily adjusted to use metal of various widths.

Various changes may be made without departing from the spirit of my invention as claimed.
